The Siemens MAMMOMAT series with OPDIMA option is intended for use in small field mammographic X-ray imaging (SFDM). Such small field imaging is used during stereotactic biopsy and diagnostic spot localization.
OPDIMA is a Small Field Digital Mammography (SFDM) system. It is marketed as an option to the Siemens MAMMOMAT Novation X-ray examination system. It provides spot imaging for diagnosis and stereotactic biopsy. OPDIMA features a small (49 x 85 mm²) CCD detector that converts the X-ray attenuation into an electronic pattern. The electronic pattern is read out, processed, and displayed on a high resolution monitor. The images may be post processed, printed, or transferred via DICOM network for multiple purposes.
The provided text is a 510(k) summary for the OPDIMA Digital Mammographic X-ray System. It focuses on demonstrating substantial equivalence to previously cleared devices, primarily due to a software and workstation upgrade (moving from UNIX to Windows). It does not contain information about specific acceptance criteria or a study proving the device meets those criteria, as it's a special 510(k) focused on a software change rather than initial device performance.
Therefore, I cannot fulfill most of your request from the provided text. The document does not describe the types of studies you've requested (e.g., standalone performance, MRMC comparative effectiveness, sample sizes for test/training sets, ground truth establishment, or expert details) because it's not a de novo submission or a traditional 510(k) for a new device requiring extensive clinical performance data for first-time market clearance.
However, I can extract the following limited information:
1. Table of Acceptance Criteria and Reported Device Performance:
This document does not present acceptance criteria or reported device performance in the format of a clinical study or a table demonstrating specific metrics against predetermined thresholds. It states that the "imaging characteristics" and "device dependent image processing remain unchanged" from the predicate devices.
2. Sample size used for the test set and the data provenance:
Not specified in this document. This 510(k) is for a software upgrade, not a new imaging performance study.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
Not applicable/specified in this document.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
Not applicable/specified in this document.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
No MRMC study is mentioned. This device is a digital mammographic X-ray system, not an AI-assisted interpretation tool.
6. If a standalone (i.e. algorithm only, without human-in-the-loop performance) was done:
Not applicable/specified in this document. This device is a hardware system with associated software, not a standalone algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
Not applicable/specified in this document.
8. The sample size for the training set:
Not applicable/specified in this document.
9. How the ground truth for the training set was established:
Not applicable/specified in this document.
Summary of what the document does provide concerning performance/equivalence:
- Claim of unchanged imaging characteristics: "The OPDIMA functionality, the technology characteristics of the system, with the new Windows based workstation remain unchanged for the imaging characteristics."
- Resolution: Maximum resolution (high res mode 2044 x 3584 pixel) with 20 lp/mm and with 13 lp/mm (normal res mode 1024 x 1792 pixel) remains unchanged.
- Image processing: Device dependent image processing remains unchanged.
- Predicate Devices: K003945 (OPDIMA Digital Mammographic X-ray system) and K071015 (OPDIMA Digital Mammographic x-ray system) are cited as predicates, implying that the performance of the current device is considered equivalent to these previously cleared devices.
This 510(k) essentially argues that changing the underlying operating system and workstation environment does not alter the fundamental imaging performance of the OPDIMA system, therefore extensive new clinical performance data is not required.

It provides spot imaging for diagnosis and stereotactic biopsy. OPDIMA features a small (49 x 85 mm²) CCD detector that converts the X-ray attenuation into an electronic pattern. The electronic pattern is read out, processed, and displayed on a high resolution monitor. The images may be post processed, printed, or transferred via DICOM network for multiple purposes.
5. Intended Use of the Device:
The Siemens MAMMOMAT series with OPDIMA option is intended for use in small field mammographic X-ray imaging. Such small field imaging is used during stereotactic biopsy and diagnostic spot localization.
Technology Characteristics of the principle Device Compared to the 6. Predicate:
The OPDIMA functionality, the technology characteristics of the system, with the new Windows based workstation remain unchanged for the imaging characteristics. Graphical user interface and performance will improve to keep pace with the technology leap. The imaging area (49x85mm²) remains the same. The maximum resolution (high res mode 2048 x 3584 pixel) with 20 lp/mm and with 13 lp/mm (normal res mode 1024 x 1792 pixel) remains unchanged. Device dependent image processing remains unchanged. Each software module that is reused in the new Windows based workstation is converted to the Windows environment.
The OPDIMA software will run on the AWS of the MAMMOMAT Novation as an additional software module. The FFDM functionality will be disabled while the OPDIMA is in use.
7. General Safety and Effectiveness Concerns
Instructions for use are included within the device labeling and the information provided will enable the trained healthcare professional to operate the device in a safe and efficacious manner. Furthermore the operators are health care professionals familiar with and responsible for the X-ray examination to be performed.
8. Substantial Equivalence

Dear Ms. Rendon:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Spocial Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
